SPECIFICATION formingpart of Letters Patent No; 413,653, dated October 29, 1889. Application filed August 13, 1888. Serial No. 282,444. (No model.)

To all whom it may concern.-

Be it known that 1, Games F. FILLEY, of St; Louis, Missouri, have made a new and useful Improvement in Heating-Stoves, of which the following is a full, clear, and exact description. The improvement relates more especially to that class of heating stoves termed boxstoves, a familiar type of heating-stove consisting, substantially, of a horizontallyextended combustion-chamber having no ashpit separated therefrom, and provided at one end with a door for the introduction of the fuel, and at the otherend with an exit for the escape of the products of combustion.

.The improvement is twofold. It consists, partly, in a novel means for generating and promoting a hot-air current, and partly in a cross-section of the stove-body.

out the stove.

The same letters of reference denote the same parts.

Saving as it is modified by the present improvement, the stoveA is of the usual description, it having the bottom a, the sides a a, the top a the door a in thefront end a, and

the direct escape a inthe rear end a", and supported upon the legs a Y B representsa flue extending longitudinally in the combustion-chamber G from end to end thereof,and at its ends I) 19 passing through the front and rear ends, respectively, of the stove and communicating with the atmosphere with- The flue is preferably arranged near the top of the chamber 0, but separated therefrom, so that the entire external surface of the flue shall be exposed to theheat of the chamber- G.

A featureof the flue is constructing it so that the exit therefrom shall be higher than the inlet thereinto. By this means a more vigorous circulation of air through the'flue is obtained than when the ends of the flue are The most desirable mode,

provement is by carrying the exit end of the flue upwardwithin the chamber U, as thereby such upwardly-extended part is exposed to the heat of the chamber 0, and perhapsthe improvement is most conveniently carried out by making the upwardly-extended part B of the flue to pass upward through or to connect .with the opening a in the top of the stove,

substantially as shown in Figs. 1 and 2 The air from without the stove then passes into the flue at both ends I) 1) thereof, and then however, of carrying out this part of the im As shown in the drawings, the inlet or in- A lets into the flue B are for the air-space surrounding the stove.

Instead of extending the combustion-chamber laterally to the sidewalls a a of the stove, a circuitous flue D D is formed at each side of the chamber 0, by which means and by closing the direct escape a by means of a suitable damper G the heat-currents generated within the chamber 0 can be taken forward and backward directly againstthe side walls a 01/, and afterward discharged at the rear end of the stove into a flue E, which extends upward without the rear end of the stove, and thence outward therefrom at e. The special construction of this flue D D is a feature of the present improvement.

In the Todd heating-stove a flue has been carried alon g the side of the combustion-chamber toward the forward end of the stove and thence downward beneath the combustionchamber, and then along the bottom of the stove to an escape-flue at the rear end of the stove; but when such a flue is used and such a course given to the heat-currents a large should be radiated more exclusively, if not wholly, from the sides ofthe stove. To this end I make the inlet (1 into the part D of the flue at the rear end of the combustion-chamber, and I extend the part D forward to the front end of the stove,tl1'en extend it downward at d, and then extend it backward to the rear end of the stove; but this rearwardly-extended part Di of the flue is carried along the side of the stove and it is not allowed to extend under the stove, and the heat therefrom, as well as that from the part D, is radiated directly laterally from the stove. The flue part D at its farther end communicates with the flue E.

Either of the above-described features is valuable by itself, and the two in combination are especially useful. The flue B tends to prevent the heat of the combustion-chamber from being radiated directly upward, and the I air-flue tends to increase the efficiency of the stove.

The flue B, constructed as described, is useful in other forms of stoves than the one here shown.

The urn F, or whatever construction is used above the exit from the flue part B, is suitably perforated or otherwise made to provide for the escape of the hot air from the flue B.

I claim As an article of manufacture, the hereindescribed heating-stove having the T-shaped hot-air flue B B in the top of its combustionchamber, the circuitous smoke-flue D D, and the escape-flue E, into which said smoke-flue discharges, substantially as specified.
